T 0 all '10 71 (mt it may con cern Be" it known that I, C'i-Insrnn Al HAG/An, residing at New York, county'of Bronx, and State of New York, 'haiv e invented certain new and useful Improvements in"a"'l i indow Lock,ofwhichthe tol'lowing is a'sp'ecification.

My invention relates to window locks and more especially'to alocl: to be applied to windows eomprising'two or more ,frames in' mountedp arallel groovesj Vith such win dows it'is desirable that means be provided by which the" frames, which are relatively movable to an overlying position,may' be held against such movement so as to provide a locked closure for the aperture tOprevent unauthorized entry.

The one object ofm'y invention is to pro Vid'e' such awin'dow lock which shall be of an attractive appearance'and which shall be effective in preventing the're'lative movement of the window framesf T he/second objectot myinvention is to provide a window lock which may be installed on a window frame'withYa nl-ini'niuni of operations, which maybe adjustedso as to permit'com'plete freedom of m'oven'iei'itof= the frames, and which may be brought into operative position so as'to prevent unauthor ized 'moveme'nt- Another object of the invention-isto pro' vide asecure means for locking'a window" against unauthorized movement" which shall at the same time pro'videthemeans bywhi'ch" the window may be'slightly openedforven tilati'on purposes. I

Another object of theinventionis to =pr'ovide a lock applicable'to prevent the rela" tive movement'to over-lying position of apair of window frames, the'lock being of" such character that it cannot'be' picked 'or manipulated from without' the building' and" offering no' means by which it maybe pried" or otherwise forced out of position; v

Other objects and aimsof the invention moreorless specific than those referred to above, willbe in part obvious andin part pointed out in the'course of the following description of the elements, combinations, arrangements of parts and] applications of principles, constitut'ii' g' the invention and the scope of protectioncontemplated will be indicated'in the appended claims.

Inthe" drawingsinwhichI show a preferred form of my invention Figure 1 is a cross-sectional view, with bar of the adjacent frame;

parts brolsfen away, of a pair of window .trames showing my lock in operative position;

7 r guie 2 1s a,cross-sec t onal v ew of part of a'wlndow frame taken on a line through,

characters designate similar; parts Ithrou'gh out'the several views; thereofthe reference numeral 1 indicates a window frame in" which is mounteda sheet of glass,il eld in place by fillets or moldings in theusual manner. The window frame as shown in; Figure (Sis mounted in wall of the build ing so as'fto slide in suitable grooves 'in a larger litram 'e mounted in the aperture in the wall. Lying" adj acent'fto "frame" is :frame 4 constructed in the samemanner as fra ne l 1 and forming in this case, thelov'i er half of thef'window. j The frames1and a1ar'so, mounted as tobe relativelyni'ovable to aphsition'overlying each other. F ItQwillt'be seen that when the frames are'in the over-lying position the aperture l in the building is, in; the case of a two part' window, but half closed. Q N WVith-windows such as are hereclescribed it is desirable tl ati reedom of'moveme'nt' be maintained so that the wind'ows vmay be] raised or lowered "so as to provide for V611. tilation in the building; It is desirable furtherthat some means should be provided by v i, a i z 1 whichthe two halves of the w ndow may be locked againstrelative'movement, espef cially in the night-time "in order that intrud ers may be prevented from" entering ,the b uldingf Window iloclts are'provided for this purpose and the ordinary forms consist of acamm ed wedge mounted on one of the bars at .the frame and engaging a, suitable hooked iiizlger mounted von the corresponding fwhenthe' win, dow is to belocked the wedge is rotated'or otherwise moved so as to engage the finger. Such locking means are open to a number of objections, one of which being that such a lock may be easily picked or otherwise manipulated from without the building so as to permit the window to be opened. A second objection is that the window must be closed before the lock may be operated and this makes it impossible to secure ventilation by means of the window when locked.

Thelocking means which is here described overcomes both of the objections stated and in order to mount the new and improved lock in the window, it is only necessary to bore a hole 5 through one of the side bars 6 of the window frames at a point relatively near the cross bar '7 which overlies the adjacent frame. On either face of the upright bar 6 there are then mounted face plates 8 and 9, these plates being provided with apertures registering with the bore through the framef These plates are secured to the frame in any suitable manner as with screws.

In the plate 8 previous to its attachment to the window frame, there is mounted a bolt 10, held in position in the plate by means of a pin 11 whichextends through the bolt and projects from either surfacethereof to engage the plate 8. The plate 8 is provided with a suitable lateral flange 12, about the aperture, the flange projecting a short distance into the bore in the frame to guide the bolt in its movement. The marginal edge of the aperture in the plate 8 is also reamed as indicated at 18 to provide a seat.

On one end of the bolt there is provided a smooth knob 14 which makes a close lit with the reamed surface or seat on the plate 8 .when the bolt is in operative position as shown in Figure 2. The plate 8 is to be mounted in the frame so that the knob 14 of bolt 10 is on the outer surface of the window. On the inner end of the bolt, there is provided suitable locking means which consists in part, of a diametrical bore 15 through the bolt located a short distance from the end opposite the knob. The end surface of the bolt is also diametrically channeled as designated at 16 so that the end of the bolt may be con sidered as being diametrically slotted and provided with pin 17 mounted between the walls of the slot. The shape of the bore 15 and channel 16 is such that there may be mounted in the inner end of thebolt a. suitable locking means such as a padlock 18, the locking arm of which, 19. may be inserted through the bore 15 so as to engage about the locking pin 17. lVith the padlock in operatire position, the bolt is held against movement against the frame and the padlock is held between and against the walls of the slot so as to project almost at right angles of the frame. With the lock in this position, it will be clear that the second frame 4 when being moved so as to occupy an overlying position relatively to the frame 2 cannot be moved beyond the lock, inasmuch as the end of the bolt and the lock project into the path of the frame 4:.

As the second frame may be moved only till it engages the bolt it will be desirable to mount the look a slight distance above the cross bar 7 as shown in Figure 6, since with the lock in, this position, slight relative movement of the two frames is permitted so as to provide for ventilation. However, when the lock is in operation the frames cannot be moved to a complete overlying position so as to permit unauthorized entrance through the window aperture.

When it is desired to unlock the window to permit it to be opened to its fullest extent the key 20 is used to release the lock and it is then removed from the bolt. permits the bolt 10 to be moved to the position shown in Figure 3 in which the inner end of the bolt lies flush with the inner face plate 9. When the bolt is in this position,

it will be clear that the two windows may be moved to any position as freely as though the lock were not mounted on the frame. It is desirable of course, that some means he provided by which the bolt may be readily withdrawn from the bore in the frame and to this end there is formed a shallow notch 21 in one of the walls of the slot in the end of the bolt. On the end of the key there is also provided a small lateral lug 22 which may be inserted in the notch so as to draw the bolt from the bore to such a position that the padlock may be attached.

It will be seen that my invention provides a safe locking means for window frames which permits the window to be locked against entry while at the same time permitting a slight relative movement of the frames, for ventilation purposes. It will be noted further that the lock may be mounted at any point in the side bar of the window frame, preferably at a short distance from the cross bar, the distance at which the lock is mounted from the cross bar determining the extent to which the frames are capable of relative movement. Ordinarily four and five inches of travel will be sufficient for ventilating purposes.

With the locks hither-to in use it has been comparatively simple to insert a slender instrument between the frames so as to move the parts of the look so that the window may be opened. lVith the new lock hitherto in use it has been comparatively simple to insert a slender instrument between the frames so as to move the parts of the look so that the window may be opened.

With the new look herein described it is impossible for any unauthorized person to unlock the window, especially from the outside. Furthermore all exposed parts are provided with smooth rounded surfaces and This . installed on windows prior to their mounting in the window aperture or.it may be in stalled on a window already in use. It is also to be noted that" all the parts of the lock are mounted on a single frame of the window so that it is not necessary to provide for careful adjustment such as is necessary in two part locks in which one part is mounted on each frame. Any suitable locking means may be provided for the bolt but I find that a padlock engaging a pin in the slot in the inner end of the bolt is a simple and effective arrangement. l/Vhile the lock has been shown in use on a window in which two frames are used, it will be clear that it is capable of application to windows having a plurality of frames, though in such cases number of lock must be used depending of course on the number of frames it is desired to lock against relative movement.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
